Genes affected

TSPAN5 (HGNC:17753): (tetraspanin 5) The protein encoded by this gene is a member of the transmembrane 4 superfamily, also known as the tetraspanin family. Most of these members are cell-surface proteins that are characterized by the presence of four hydrophobic domains. The proteins mediate signal transduction events that play a role in the regulation of cell development, activation, growth and motility. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.610G>A (p.A204T) alteration is located in exon 6 (coding exon 6) of the TSPAN5 gene. This alteration results from a G to A substitution at nucleotide position 610, causing the alanine (A) at amino acid position 204 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
